BACKGROUND

OneM2M Standards Organization is dedicated to specifying a unified service-level standard oriented to a plurality of Internets of Things. The OneM2M TS-0001 functional architecture defines an overall framework of the protocol and defines three categories of functional entities: an Application Entity (AE), a Common Service Entity (CSE), and a Network Service Entity (NSE). Between the Application Entity (AE) and the Common Service Entity (CSE), between the Common Service Entity (CSE) and the Common Service Entity (CSE), and between the Common Service Entity (CSE) and the Network Service Entity (NSE), interaction is performed through a Request Primitive and a Response Primitive.

In an interactive process of the non-blocking request synchronization, having received a resource index Req-Ref, a requestor needs to send a request to the resource index Req-Ref multiple times, attempting to retrieve an execution result, and correspondingly, a receiver should send a response of execution uncompleted to the requestor for many times, which, thus, increases workload of the requestor and the receiver, and increases apparatus power consumption of the requestor and the receiver.

DETAILED DESCRIPTION

In order to make objects, technical details and advantages of the embodiments of the invention apparent, the technical solutions of the embodiments will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the invention. Apparently, the described embodiments are just a part but not all of the embodiments of the invention. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the invention.

Here, it should be noted that in the drawings, the same reference signs are given to component parts which basically have same or similar structures and functions, and repetitive description about them is omitted.

The OneM2M defines three interactive modes: blocking request, non-blocking request synchronization and non-blocking request asynchronization. FIG. 1A, FIG. 1B and FIG. 1C respectively show the three interactive modes, and show difference among the three interactive modes.

As shown in FIG. 1A, the blocking request refers to that after a requestor sends a request, session connection is maintained, until an execution result response sent by a receiver is received. As shown in FIG. 1B, the non-blocking request synchronization refers to that after the requestor sends the request, the receiver immediately sends a response to notify the requestor that the request has been successfully received, then after having received the response message sent by the receiver for a period of time, the requestor initiatively sends a request to the receiver to retrieve an execution result. As shown in FIG. 1C, the non-blocking request asynchronization refers to that, after the requestor sends the request, the receiver immediately sends the response to notify the requestor that the request has been successfully received, then after having completed execution, the receiver sends an execution completion notification carrying the execution result to the requestor. The non-blocking request synchronization and the non-blocking request asynchronization are applicable to different scenarios, the non-blocking request synchronization is applicable to a scenario where the requestor cannot receive a notification message, and the non-blocking request asynchronization is applicable to a scenario where the requestor can receive the notification message.

FIG. 2 shows a general interactive process of the non-blocking request synchronization. Firstly, in step S1, the requestor sends a resource request; in step S2, the receiver creates a request resource, and records detailed information of the resource request in the request resource, and at the same time, creates a resource index Req-Ref; in step S3, the receiver returns the resource index Req-Ref to the requestor; in step S4, the receiver executes the request resource; in step S5, the requestor sends an execution result retrieving request to the resource index Req-Ref; in step S6, since the receiver has not yet completed execution of the non-blocking request, the receiver sends a response of request execution uncompleted to the requestor; in step S7, the requestor, after a period of time, again sends an execution result retrieving request to the resource index Req-Ref; in step S8, since the receiver has not yet completed the execution of the non-blocking request, the receiver sends a response of request execution uncompleted to the requestor; in step S9, the receiver completes execution of the non-blocking request and records the execution result; in step S10, the requestor again sends an execution result retrieving request to the resource index Req-Ref; in step S11, the receiver sends the execution result response to the requestor.

In the interactive process of the non-blocking request synchronization as shown in FIG. 2, after having received the resource index Req-Ref, the requestor cannot predict an execution completion timestamp of the receiver, and needs to send the request attempting to retrieve the execution result to the resource index Req-Ref multiple times, and correspondingly, the receiver should send the response of execution uncompleted to the requestor for many times, so workload of the requestor and the receiver is increased, and apparatus power consumption of the requestor and the receiver is increased.

Therefore, it is necessary that the workload and the apparatus power consumption of the requestor and the receiver caused by frequent execution result retrieving request in the non-blocking request synchronization interactive process can be reduced.

Hereinafter, the non-blocking request processing method according to the embodiment of the present disclosure will be described below from the perspective of the receiver and the requestor, respectively.

Firstly, with reference to FIG. 3A, the non-blocking request processing method according to the embodiment of the present disclosure is described from the perspective of the receiver.

In step S31, the receiver receives the non-blocking request from the requestor.

In step S32, the receiver determines the execution completion estimated timestamp of the non-blocking request.

In step S33, the receiver sends the execution completion estimated timestamp to the requestor.

The execution completion estimated timestamp may be an estimated time point when the receiver completes execution of the non-blocking request, or may be a time period from a time point when the receiver receives the non-blocking request to the estimated time point when the receiver completes the execution of the non-blocking request.

Next, with reference to FIG. 3B, the non-blocking request processing method according to the embodiment of the present disclosure is described from the perspective of the requestor.

In step S36, the requestor sends the non-blocking request to the receiver.

In step S37, the requestor receives the execution completion estimated timestamp of the non-blocking request from the receiver.

In the non-blocking request processing method according to the embodiment of the present disclosure, the execution completion estimated timestamp of the non-blocking request is estimated after receiving the non-blocking request and the estimated execution completion estimated timestamp is sent to the requestor, so that the requestor can roughly understand an expected execution completion timestamp of the non-blocking request, which avoids a case where the requestor continuously sends the execution result retrieving request so as to attempt to retrieve the execution result.

Hereinafter, the interactive process between the requestor and the receiver according to the embodiment of the present disclosure will be described with the OneM2M protocol as an example.

According to the embodiment of the present disclosure, the requestor may be an Application Entity (AE), and the receiver may be a Common Service Entity (CSE); or the requestor may be a Common Service Entity (CSE), and the receiver may be a Common Service Entity (CSE); or the requestor may be a Common Service Entity (CSE), and the receiver may be a Network Service Entity (NSE).

In the present specification, the non-blocking request processing method according to the embodiment of the present disclosure will be described with the requestor being the Application Entity (AE), and the receiver being the Common Service Entity (CSE) as an example.

FIG. 4 shows the interactive process between the requestor and the receiver according to the embodiment of the present disclosure.

In step S41, the requestor sends the non-blocking request to the receiver, and the receiver receives the non-blocking request.

In step S42, the receiver determines the execution completion estimated timestamp of the non-blocking request. Optionally, the receiver also creates the request resource, and creates the resource index Req-Ref. In addition, optionally, detailed information of the resource request may also be recorded in the request resource. For example, under the OneM2M protocol, the request resource (<request>) may record relevant information of the non-blocking request, including: the requestor, the receiver, a request ID, a request content, a request status, a request execution result, and so on.

In step S43, the receiver sends the execution completion estimated timestamp of the non-blocking request to the requestor. Optionally, the receiver sends the created resource index Req-Ref and the execution completion estimated timestamp of the non-blocking request to the requestor simultaneously, and the requestor receives the resource index Req-Ref and the execution completion estimated timestamp.

Then, in step S441, the requestor waits for the execution completion estimated timestamp.

At the same time, in step S442, the receiver executes the received non-blocking request and records the execution result.

In step S45, the requestor sends the execution result retrieving request to the receiver, and the receiver receives the execution result retrieving request, the execution result retrieving request being used for retrieving the execution result of the non-blocking request. Optionally, the requestor sends the execution result retrieving request with respect to the resource index Req-Ref to the receiver.

In step S46, the receiver sends the execution result of the non-blocking request to the requestor, and the requestor receives the execution result.

In the non-blocking request processing method according to the embodiment of the present disclosure, the execution completion estimated timestamp of the request is sent to the requestor, the requestor may, after waiting for the execution completion estimated timestamp, sends the execution result retrieving request to the receiver, so as to avoid the case where the requestor continuously sends the execution result retrieving request to attempt to retrieve the execution result, and reduce the workload and the apparatus power consumption of the requestor and the receiver caused by the frequent execution result retrieving request.

It should be understood that, the OneM2M protocol is based on a resource, the receiver creates the request resource and creates the resource index, and then information interaction is performed between the requestor and the receiver through the resource index. However, other protocols to which the non-blocking request is applied may not be based on the resource, in which case, the receiver does not need to create the request resource and create the resource index, that is, in steps S42, S43 and S45, the contents of creation of the request resource and interaction with the resource index are not required, but optional.

FIG. 5 shows a response primitive of the execution completion estimated timestamp of the request provided by the receiver to the requestor according to the embodiment of the present disclosure. According to the embodiment of the present disclosure, a response parameter: Result Estimated Timestamp is added to the response primitive provided by the receiver to the requestor. The result estimated timestamp response parameter is used for indicating a timestamp when the receiver completes the execution of the non-blocking request, and the requestor can retrieve the execution result of the non-blocking request.

As an example, the response primitive further includes at least part of response parameters as follows: Response Status Code, Request Identifier, content (including Req-Ref), To, From, Originating Timestamp, Result Expiration Timestamp, and Event Category.

Hereinafter, a non-blocking request processing method according to a first embodiment of the present disclosure will be described with reference to FIG. 6.

According to the first embodiment of the present disclosure, determining of the execution completion estimated timestamp of the non-blocking request according to a determination strategy of the execution completion estimated timestamp, includes: calculating the execution completion estimated timestamp of the non-blocking request according to a predetermined calculation strategy of the execution completion estimated timestamp.

According to the first embodiment of the present disclosure, the calculation strategy of the execution completion estimated timestamp is predetermined at a receiver, and the execution completion estimated timestamp of the non-blocking request is calculated according to the predetermined calculation strategy of the execution completion estimated timestamp.

In step S61, a requestor sends the non-blocking request to the receiver, and the receiver receives the non-blocking request.

In step S62, the receiver calculates the execution completion estimated timestamp of the non-blocking request according to the predetermined calculation strategy of the execution completion estimated timestamp. Optionally, the receiver creates a request resource, and creates a resource index Req-Ref, and may further record detailed information of a resource request in the request resource.

In step S63, the receiver sends the execution completion estimated timestamp of the non-blocking request to the requestor. Optionally, the receiver sends the created resource index Req-Ref to the requestor along with the execution completion estimated timestamp of the non-blocking request, and the requestor receives the resource index Req-Ref and the execution completion estimated timestamp.

Then, in step S641, the requestor waits for the execution completion estimated timestamp. At the same time, in step S642, the receiver executes the non-blocking request and records an execution result.

In step S65, the requestor sends an execution result retrieving request to the receiver, and the receiver receives the execution result retrieving request, the execution result retrieving request being used for retrieving the execution result of the non-blocking request. Optionally, the requestor sends the execution result retrieving request with respect to the resource index Req-Ref to the receiver.

In step S66, the receiver sends the execution result of the non-blocking request to the requestor, and the requestor receives the execution result.

According to the first embodiment of the present disclosure, the predetermined calculation strategy of the execution completion estimated timestamp may take into account at least one of: a request ideal execution timestamp, task priority and receiver load capacity, that is, the execution completion estimated timestamp is calculated by the predetermined calculation strategy of the execution completion estimated timestamp according to at least one of the request ideal execution timestamp, the task priority and the receiver load capacity. Further, according to the first embodiment of the present disclosure, the receiver load capacity may include at least one of: a processor occupancy rate, a memory occupancy rate, and a network occupancy rate.

For example, with respect to each non-blocking request received by the receiver, the non-blocking request may be divided into request types below according to the resource it needs: a processor consumption type, a memory consumption type, a network consumption type, a processor and memory consumption type, a processor and network consumption type, a memory and network consumption type, and a processor and memory and network consumption type.

With respect to the non-blocking request received by the receiver, the ideal execution timestamp of the non-blocking request may be calculated according to the number of instructions of the non-blocking request and a unit instruction execution timestamp.

Preferably, with respect to each non-blocking request, the execution completion estimated timestamp of the non-blocking request may be calculated according to the ideal execution timestamp of the non-blocking request, a delay timestamp of the task priority corresponding to the non-blocking request, and a delay timestamp of the receiver load capacity corresponding to the non-blocking request.

According to the first embodiment of the present disclosure, with respect to non-blocking requests of different request types, specific embodiments of the receiver load capacity are also different.

Specifically, with respect to the non-blocking request of the processor consumption type, the receiver load capacity includes the processor occupancy rate; with respect to the non-blocking request of the memory consumption type, the receiver load capacity includes the memory occupancy rate; with respect to the non-blocking request of the network consumption type, the receiver load capacity includes the network occupancy rate; with respect to the non-blocking request of the processor and memory consumption type, the receiver load capacity includes the processor occupancy rate and the memory occupancy rate; with respect to the non-blocking request of the processor and network consumption type, the receiver load capacity includes the processor occupancy rate and the network occupancy rate; with respect to the non-blocking request of the memory and network consumption type, the receiver load capacity includes the memory occupancy rate and the network occupancy rate; and with respect to the non-blocking request of the processor and memory and network consumption type, the receiver load capacity includes the processor occupancy rate, the memory occupancy rate and the network occupancy rate.

FIG. 7 shows a schematic table of calculation of the execution completion estimated timestamp according to the first embodiment of the present disclosure. It should be noted that: “×” is a multiplication operation symbol, and “+” is an addition operation symbol.

For example, with respect to the non-blocking request of the processor consumption type, the execution completion estimated timestamp may be: unit instruction execution timestamp (a1 microseconds/instruction)×the number of instructions for the non-blocking request (a2 instruction)+delay timestamp corresponding to task priority of the non-blocking request (t1x)+delay timestamp corresponding to a current processor occupancy rate (t2x).

For example, with respect to the non-blocking request of the memory consumption type, the execution completion estimated timestamp may be: unit instruction execution timestamp (b1 microseconds/instruction)×the number of instructions for the non-blocking request (b2 instruction)+delay timestamp corresponding to task priority of the non-blocking request (t1x)+delay timestamp corresponding to a current memory occupancy rate (t3x).

For example, with respect to the non-blocking request of the network consumption type, the execution completion estimated timestamp may be: unit instruction execution timestamp (c1 microseconds/instruction)×the number of instructions for the non-blocking request (c2 instruction)+delay timestamp corresponding to task priority of the non-blocking request (t1x)+delay timestamp corresponding to a current network occupancy rate (t4x).

Next, a non-blocking request processing method according to a second embodiment of the present disclosure will be described with reference to FIG. 8.

According to the second embodiment of the present disclosure, after having prerecorded the execution completion timestamp of various categories of historical requests, and received the non-blocking request from the requestor, the receiver determines the execution completion estimated timestamp of the non-blocking request received currently according to the execution completion timestamp of various categories of historical requests recorded.

In step S81, the requestor sends the non-blocking request to the receiver, and the receiver receives the non-blocking request.

In step S82, after having received the non-blocking request, the receiver determines the execution completion estimated timestamp of the non-blocking request according to the execution completion timestamp of various categories of historical requests recorded. Optionally, the receiver creates a request resource, and creates a resource index Req-Ref, and may further record detailed information of a resource request in the request resource.

Optionally, the receiver sends the created resource index Req-Ref to the requestor along with the execution completion estimated timestamp of the non-blocking request, and the requestor receives the resource index Req-Ref and the execution completion estimated timestamp.

Then, in step S841, the requestor waits for the execution completion estimated timestamp. At the same time, in step S842, the receiver executes the non-blocking request and records an execution result.

In step S85, the requestor sends the execution result retrieving request to the receiver, and the receiver receives the execution result retrieving request, the execution result retrieving request being used for retrieving the execution result of the non-blocking request. Optionally, the requestor sends the execution result retrieving request with respect to the resource index Req-Ref to the receiver.

In step S86, the receiver sends the execution result of the non-blocking request to the requestor, and the requestor receives the execution result.

Hereinafter, the method for determining the execution completion estimated timestamp of the non-blocking request according to the execution completion timestamp of various categories of historical requests recorded according to the second embodiment of the present disclosure will be described with reference to FIG. 9.

Step S91: selecting at least one historical request matching with the non-blocking request.

Optionally, the at least one historical request that exactly matches with the non-blocking request may be selected, or the at least one historical request that matches with the non-blocking request to a higher degree may be selected, according to the request type and a request operation object of the non-blocking request.

FIG. 10 shows the request type and the request operation object of the various categories of historical requests as well as a historical execution completion timestamp according to the second embodiment of the present disclosure.

For example, according to the OneM2M protocol, the request type of the non-blocking request may include: Create, Retrieve, Update, Delete, and Notify.

For example, according to the OneM2M protocol, the request operation object of the non-blocking request may include: CSEBase, AE, remoteAE, container, and so on.

Step S92: retrieving the historical execution completion timestamp of the at least one historical request.

Step S93: determining the execution completion estimated timestamp of the non-blocking request, according to the historical execution completion timestamp of the at least one historical request.

As shown in FIG. 10, one historical request close to the non-blocking request is selected according to the request type and the request operation object of the non-blocking request, and the historical execution completion timestamp of the historical request is taken as the execution completion estimated timestamp of the non-blocking request.

In addition, for example, when a plurality of historical requests that are close to the non-blocking request are selected according to the request type and the request operation object of the non-blocking request, a maximum value of the historical execution completion timestamp of the plurality of historical requests may be selected as the execution completion estimated timestamp of the non-blocking request; or an average value of the historical execution completion timestamp of the plurality of historical requests may be selected as the execution completion estimated timestamp of the non-blocking request.

For another example, when the plurality of historical requests that are close to the non-blocking request are selected according to the request type of the non-blocking request, the maximum value of the historical execution completion timestamp of the plurality of historical requests may be selected as the execution completion estimated timestamp of the non-blocking request.

Hereinafter, a non-blocking request processing method according to a third embodiment of the present disclosure will be described with reference to FIG. 11.

According to the third embodiment of the present disclosure, determining of the execution completion estimated timestamp of the non-blocking request according to a determination strategy of the execution completion estimated timestamp, includes: determining the execution completion estimated timestamp of the non-blocking request received according to the execution completion estimated timestamp of various categories of non-blocking requests.

According to the third embodiment of the present disclosure, having preset the execution completion estimated timestamp of the various categories of non-blocking requests, and received the non-blocking request from the requestor, the receiver takes the execution completion estimated timestamp of a category of non-blocking requests closest to the non-blocking request received as the execution completion estimated timestamp of the non-blocking request received.

In step S111, the requestor sends the non-blocking request to the receiver, and the receiver receives the non-blocking request.

In step S112, the receiver determines the execution completion estimated timestamp of the non-blocking request received according to the preset execution completion estimated timestamp of the various categories of non-blocking requests. Optionally, the receiver creates a request resource, and creates a resource index Req-Ref, and may further record detailed information of a resource request in the request resource.

For example, the receiver may categorize the non-blocking request received according to the request type, or according to the request type and the request operation object, to determine the request category of the non-blocking request received currently, and takes the preset execution completion estimated timestamp corresponding to the request category as the execution completion estimated timestamp of the non-blocking request received currently.

In step S113, the receiver sends the execution completion estimated timestamp of the non-blocking request to the requestor. Optionally, the receiver sends the created resource index Req-Ref to the requestor along with the execution completion estimated timestamp of the non-blocking request, and the requestor receives the resource index Req-Ref and the execution completion estimated timestamp.

Then, in step S1141, the requestor waits for the execution completion estimated timestamp. At the same time, in step S1142, the receiver executes the non-blocking request and records an execution result. Optionally, in step S1142, the receiver updates the execution completion estimated timestamp of the category corresponding to the non-blocking request according to an actual execution completion timestamp of the non-blocking request.

In step S115, the requestor sends the execution result retrieving request to the receiver, and the receiver receives the execution result retrieving request, the execution result retrieving request being used for retrieving the execution result of the non-blocking request. Optionally, the requestor sends the execution result retrieving request with respect to the resource index Req-Ref to the receiver.

In step S116, the receiver sends the execution result of the non-blocking request to the requestor, and the requestor receives the execution result.

According to the third embodiment of the present disclosure, determining of the execution completion estimated timestamp of the non-blocking request received according to the execution completion estimated timestamp of various categories of non-blocking requests, includes: the receiver may categorize the non-blocking request received according to the request type, or according to the request type and the request operation object. The execution completion estimated timestamp matching with the request category of the non-blocking request is determined from corresponding relationship between the request category and the execution completion estimated timestamp, as the execution completion estimated timestamp of the non-blocking request received.

As described before, according to the request type, the non-blocking request may be divided into: create, retrieve, update, delete, and notify. With respect to each request type, the execution completion estimated timestamp of the request type may be preset, or the execution completion estimated timestamp of the request type may be calculated in real time. For example, with respect to each request type, the execution completion estimated timestamp of the request type may be preset according to the maximum value of the historical execution completion timestamp of respective historical requests of the request type. Or, the maximum value of the historical execution completion timestamp of respective historical requests of the request type may be determined in real time, and the maximum value is taken as the execution completion estimated timestamp.

FIG. 12 shows an example of presetting the execution completion estimated timestamp of the request type for each request type according to the third embodiment of the present disclosure.

Alternatively, as described above, according to the request operation object, each request type may be further divided into a plurality of request sub-types: CSEBase, AE, remoteCSE, container, etc. With respect to each request sub-type, the execution completion estimated timestamp of the request sub-type may be preset according to a maximum value of the historical execution completion timestamp of respective historical requests of the request sub-type. With reference to FIG. 10, t11, t12, . . . t54, etc. may respectively represent maximum historical execution completion timestamps corresponding to the respective request sub-types.

Specifically, after execution of the non-blocking request is completed each time, in a case where the actual execution completion timestamp of the non-blocking request is greater than the preset execution completion estimated timestamp of the request category (i.e., the request type or the request sub-type) corresponding to the non-blocking request, the preset execution completion estimated timestamp of the request category (i.e., the request type or the request sub-type) corresponding to the non-blocking request is updated to the actual execution completion timestamp of the non-blocking request; on the contrary, in a case where the actual execution completion timestamp of the non-blocking request is not greater than the preset execution completion estimated timestamp of the request category (i.e., the request type or the request sub-type) corresponding to the non-blocking request, the preset execution completion estimated timestamp of the request category (i.e., the request type or the request sub-type) corresponding to the non-blocking request remains unchanged.

It should be understood that, the OneM2M protocol is a protocol based on the resource request, the receiver creates the request resource and creates the resource index, and then information interaction is performed between the requestor and the receiver through the resource index. However, other protocols to which the non-blocking request is applied may not be based on the resource request, in which case, the receiver does not need to create a resource and create the resource index, that is to say, from the first embodiment to the third embodiment of the present disclosure, in steps S62, S63, S65, S82, S83, S85, S112, S113, and S115, the contents of creation of the request resource and interaction with the resource index are not required.
